SPECIFICATION forming part of Letters Patent No. 353,729, dated December'7, 1886.

Application filed July 28, 1886. Serial No. 209,285. (No model.)

To all whom it may concern:

Be it known that I, JOHN A. BANOROFT, of the city of XVorcester, countyof \Vorcester,

and State of Massachusetts,have invented certain new and usefulImprovements in Street'- Sprinklers; and I do hereby declare thefollowing to bea 'full, clear, and exact description of the same,reference being had to the accompanying drawings and the letters ofreference marked thereon, forming a part of this specification, and inwhich- Figure 1 represents a side view of a streetsprinkler having mypresent improvements applied thereto, the end of the pole being brokenoff. Fig. 2 represents a longitudinal vertical central section of thesprinkler,as will be hereinafter more fully described, indicated by line00 m, Fig. 3. Fig. 3 represents a section of the lower half of thesprinkler, indicated byline a; x,Fig. 2. Fig. 4 represents a top or planview, upon an enlarged scale, of the combined valve. Fig. 5 represents avertical central section of the valve on line a a, Fig; 4. Fig. 6represents upon an enlarged scale a modification of the valve. Fig. 7also represents upon a like scale another valve modification; and Fig. 8represents upon an enlarged scale a vertical section through the backwater-discharge chamber, as will be hereinafter more fully described;and Fig. 9 represents upon alike enlarged scale vertical sectionsthrough the water-discharge chamber on one side, both sides being alike.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe the improvements more indetail.

The nature of my invention consists in the arrangement and combination,with the body or water-reservoir of the sprinkler, of two series ofwater'discharge chambers at the rear of the sprinkler, and also one oneach side,as will be hereinafter described.

It further consists in the combination, with each operating-lever andset of double-discharge water-chambers, of a two-way valve, whereby thewater can be shut oii' and let onto either or both the chambers at thewill ofthe operator, as will be hereinafter described.

In the drawings, A is the main water-tank, supported upon rear wheels,13, and front openings or ports.

wheels, B, in the usual manner. On thetaukbottom 0 are arranged, in thisinstance, five sets of valves, 0, C", 0 G, and C the first three setsadmitting water to the siir waterdischarge chambers D, D, D", D D, and Dand the twolatter to the side water-discharge chambers,E E and E E Eachvalve has two The rear water-discharge chambers, D, D and D, may bemadein one continuouschamberwith two divisions, (shown in dotted lines,Fig. 3,) dividing said chamher into three separate chambers; or thechambers may be made entirely separate, but arranged to abut againsteach other. The lower chambers, D, D", and D may be made in the samemanner, if preferred. One set of chambers are provided with coarseperforations 0; while the other set are providedwith fine perforationsd,and each chamber is supplied with water from the main tank by aseparate supplypipe, F, and the flow of water through two pipes iscontrolled by a single valve, as indicated in Figs. 2, 3, 4, 5, 6, and7.

In Fig. 8 are shown upon an enlarged scale vertical cross-sectionsthrough two of the rear water-discharge chambers say D and D -togetherwith portions of their water-supply pipes F F, the ends of thesupply-pipes which connect with the water-chambers being also shown insection, and Fig. 9 shows similar views of two of thesidewater-discharge chamberssay E and E -and their. water-supply pipes F F.

It will be seen that rear water-discharge chamber D is over D, D over Dand D over D also, that the side water-discharge chamber E is over E,and E over E. In this instance I form chambers E and E and E and E by adivision-plate, E. (See dotted lines, Figs. 1 and 2, and full lines,Fig. 9.) If preferred, however, two separate and distinct chambers maybe employed on each side, one chamber of each set being above or higherthan the other.

A series of valverods, G, G, G, G'", and G, are used, the rear ends ofwhich connect with their respective valves 0, C 0, C, and O in anyproper manner, while their front ends extend up and forward, and outthrough stuffing or packing boxes f in the front head, H, and are thereconnected, each to a separate hand-lever, Z, said levers extending up inconvenient positions for operation by the driver from his seat I, Ibeing his foot-board. (See Figs. 1, 2, and 3.)

Each valve is used to supply two water-discharge chambersfand the valvewhich I prefer is marked 0, Figs. 2, 3, 4, and 5, and is connected withvalve-rod G bythe bar J, provided with two slots, J J through which passthe ends of the studs J J, pins 9 9 being inserted in their upper endsto keep slotted bar J from slipping off studs J J". (See Figs. 3, 4, and5.)

Valve 0 consists of three main parts,part K receiving stud J andishinged ath to the inner end of the part K, which in turn is hinged atits outer end at h to the part K,-which receives the st ud J", and isalso hinged at its inner end at h to a'plate, h, fastened to the bottom0 of tank A. .Part K has an opening, K through its center,which isclosed by part K when the parts are in the positions shown in Figs. 4and 5, and in which case the ends of both watersupply pipes F F areclosed, part K closing the one on the left, and part K the one on theright, as seen in Fig. 5. If the driver wishes the water to flow throughthe pipe F on the left, he draws bar J forward, thereby drawing stud Jin the same direction, and turns part K upon its hinge h, when the waterwill flow under part K into supply-pipe F, and from thence into and outof discharge-chamber E, and if the driver now wishes to let water intodischarge-chamber E also,he draws barJ still farther forward, when theend 71; of part K will strike against end h of part K, and the latterwill be turned upon itshinge h,and the water will flow through hole Kinto the supply-pipe F, and through that into and-out of dischargechamber E. If, however, the driver only desires water to flow throughthe right water-s11 pply pipe,F,he forces bar J back, therebyforcing-stud J back,which turns part K up and back on its hinge h, andleaves a place under it for the water to flow into the open end of pipeF under it. This arrangement is a good one, and not liable to get out oforder.

Valve 0 Fig. 6, is a modified form of con-' struction for accomplishingthe same general results. The parts L L are hinged together by pivot an,the end m of the pivot m extending out on each side into a loop, Lfastened to the bottom 0 of the tank A- Studs L L are employed in thiscase, same as in Fig. 5; also, a slotted bar, L When the driver wishesto let water flow throughthe left-hand supplypipe, he draws bar Lforward and turns stud L and part L up and in on hinge or pivot m, andif he wishes the water to flow through both pipes F at the same time hedraws slotted bar L forward until the end m of part L strikes against.end an of part L" and lifts the part-L, so that water can flow underthat into the right hand pipe, as well as into the left-hand end one.If, however, he desires to let water into the right-hand supply-pipeonly, he forces bar L back and turns stud L and part L up and back, whenwater will flow through the righthand supply-pipe. Y I

Valves 0, O", and G arealike. The top or sliding part M of valve 0 isrepresented removed, Fig. 2, to show the openings in the bottom plate,M. This sliding or modified form of construction is shown upon anenlarged scale in Fig. 7. Plate M is formed with two side overlappingflanges, M M and under which flanges the edgesn n of the sliding part Mworks. Top part, M, has an upward projection, through which a hole ismade for the passage of the end of the operating-rod, a section of whichis shown attached in Fig. 7. With this form of valve, to let water flowthrough the left-hand pipe, the driver draws rod G forward untilthepartMhas been drawn off of the water-opening, (shown in dotted line, Fig. 7,)and if he desires to let water flow through both water-openings he drawsvalverod G forward until both water-openings are cleared; but if he onlywishes to let the water flow through the right-hand opening,-'then hepushes valve-rod G back to move part Mott the right-hand water-opening.It will thus be seen that the driver at his option can let water flowthrough both or either of the wateropenings. v

If preferred, the valve-rods and their levers I may be so arranged andconnected that levers Zwill project up through the water or' man hole N.

The operation is as follows: In sprinkling streets some places are verydry and dusty, while others being shaded or from other causes are damp,and do not require so much water. Consequently, with my presentinvention, the driver will find the lower rear sprinklers, D, D and Dsuflicient for ordinary dry streets; but if he does not let on one ormore of the upper sprinklers, D, D, and D while when p l passingcarriages. In some narrow streets the rear sprinklers are not quite wideenough to sprinkle by one passage of the cart, and two passages makesome portions of the street too wet, and by the use of the side waterchambers or sprinklers, E, E, E and E this difficulty is overcome, sinceif the street is quite narrow the rear sprinklers and one side sprinklerwill do the work by one passage of the'cart, while if still wider therear and both sidesprinklers are used. This arrangement saves much timeand expense, while the work is more uniform and satisfactory. The sidesprinklers and chambers, as before explained, are made in sets oftwo-one above the other one fine and one coarse, same as the rearsprinklers, and for the same purposes.-

In wide streets, with the use of the sidesprinklers the passage of thecart back and forth is quite suficient. Then, again, with the sidesprinklers or water-chambers, the driver in passing carriages standingnext to the curbing can sprinkle in between them, and thus in a greatmeasure keep the whole street well sprinkled, although carriages may bestanding on both sides thereof.

Having described my improvements in street-sprinklers, what I claimtherein as new, and desire to secure by Letters Patent, is

1. The combination, in a water-sprinkler, of a series of upper and lowerrear water-discharge chambers, D, D, D D D, and D" and sidewater-discharge chambers, E E and E E and a separate water-supply pipefor each water-discharge chamber, and a single valve and lever for eachset of water discharge chambers, whereby one orboth chambers of each setof water-discharge chambers can be 20 used or thrown out of action by asingle lever, substantially as and for the purposes set forth.

2. In a water-sprinkler, the combination, with each set of water-supplypipes F F, bottom 0 of the water reservoir or tank A, and 25 slotted barJ, of the parts K, K, and K hinged together at h h and to the bottom 0at h, substantially' as and for the purposes set forth.
